To ali whom t may concern:

`13e it l'rnown that we, WILLIAM ADAM Smarrita Vand TVILLIAM DoUcLAs GRAHAM,

both subjects or" the King of Great Britain, and residents, respectively, of the city of Stratford, in the county of Perth, in the Province oit' Ontario, Canadinand the'city ot Brantford, in the county ot Brant, inthe Province of Ontario,Canada, have inventedv 1 is a plan view of a Lrailway ytrack showing our roadway crossing vrapplied thereto.

Fig. 2 is an enlarged sectional view on vline 2 2, Fig. 1. f y

Fig. 8 is a cross sectional view on line 3 8, Fig. 1. i

Fig. i is a sectional detail Online 4-4 Figure 1.

- Fig. 5 1s a sectional detail on line 5-5 Figure 2. Y y

In the drawings like characters of reference indicate corresponding parts in each figure. i

land 2 indicate the rails o a railway track, and 8 the ties upon which the rails are secured in the usual manner.4 The ties 3 are spaced apart in the usual way and embedded in ballast 4;, according to common practice.

5 are inverted T bars which are secured to ties 3 and extend longitudinally thereof between and to the outside of each rail. 7 lare Inud rails which are usually located at the 8 are a series of scrap rails which are inserted and located between the rails 1 and 2 and parallel therewith, and spaced apart as indicated. The base flanges of the rails 8 are provided with cut-out portions X for passage of tongues 11.`

rThe rails 1 and 2 are supported.y upon chairs lx'and 2* in the usual manner.

The baseV flanges' 8 lie horizontally. in the Y same plane'. v f

The rails 8 Aare held in position by T bars 5 which have cut-out portions intoL which the inverted heads or" the rails 8 iitthe T bars being secured'to the .ties and-serving ,as

chair supports for the rails 8."

f 9 and 9* `are'tread plates which are suppoltel upon the basekilanges ofthe inverted rai s v yThe edges` vof the outerl plates-v9X extend parallelly' to the rails 1 and'Zand are downturned over the upper edge of the base iange "ZO of each rail 7. The centre plate 9' is provided with a series of bayonet slots '10 through which securing. bolts 10X extend having washers 10 .which are-preferably rectangular and which grip the edges of the b ase flanges 8X to hold the-centre plate in'po'- srtion. 11 are tongues which lare stamped down out of the metal ot the tread plates 9X.

Y., The' tongues 11 engage the edges ot' the base langesof the rails 8 by moving the plates 9X in a direction parallel with the rails, the y I Aplates Y sliding on they upwardlyv directed faces of the vbase flanges to the desired position. l 5 v i yIn narrow crossings the plates 9 are dispensed and in order to secure the Lplates 9) in position all that it is necessary to do is to lay a plate 9x horizontally upon the upwardly directed faces of the base flanges of the rails 8 at the ends of the railsat one side of the crossing and slide such plate longitudinally of the rails towards the centre thereofso that thel tongues 11 are in a position to pass beneath the base lianges of the rails 8 into the position shown in Fig. 6.

The other plates 9X are then similarly placed in position from the opposite ends of the rails 8. In wide crossings where a number of plates 9 extend both between and at the outside of the rails 1 and 2, we provide out out portions X in the base tlanges of the rails 8 through which the tongues 11 pass as the plate 9x is laid on the base `flanges of the rails 8. Thev plates 9X are then slid successively to their final position at one side of the crossing at the ends of the rails'S, the tongues 11 assuming the position shown in Fig. G. The centre plates 9 are then bolted in position by means of the bolts 10X passing through the slots 10, the bolts drawing the washers 10O into engagement with the lower tace of the base flanges ,o1E the rails 8. The

plates 9X at the other side of the crossing,` are then placed in position in a similar' manner to the aforementioned plates 9".

lli-.Then it is necessary to insert new ties beneath the plate 9X, the centre plate 9 is removed and one or the other ot the plates 9X slid horizontally towards the cnt out portion X of rail 8 when it can be removed by lifting, or slid oft at end of supporting rails tl.

18 are inclined plates which are provided with tongues 13X engaging the outer edges oi" the plates 9X, the lower edges of the plates 1? extending down into the ballast or to the top ot tie as indicated in Fin'. 3, adjacent to one ot the ties 3.

By this means the entrance of snow is prevented beneath the cross plates 9, and the plates are prevented 'from being lifted or dragged by obstacles dragging from cars. rlhe end edges ot the plates 13 are notched as indicated at 13* se as to fit closely to each track rail l and f2.

lfhen the rails are bonded together, as is the case in electric railways, the mud rails 7 are insulated 'om the track rails l and 2 bv a laver of alating' material 22.

llt will be seen from this description that we have provided a very simple construction ot roadway crossing which may be readilyv installwhich will freely expand or contract ur. =er climatic changes, which will be durable.. and which may be readily d wherever desired.

with the plates 9 and 9X, the base 8X of in themselves a continuous tread lslhat we claim as our invention is:

l.. The rombination with the track rails 'ooi-tina' ties. oi a series ot members between and parallel with the ils. and having' horizontally flanged ends foi-min tread bearingmeans, 'ted 'li' bars secured to the ties and extransv .fsely of the aforesaid mena.w e s, and having' cut-out portions through 'which the members extend.

The combination with track rails and sity/porting' ties, of a series of spaced apart rails 8 being placed in edge members carried by the ties parallel with the rails, plates supported upon such. members between and on the outside of each track rail, and `detachable means for connecting the plates to themembers.

3. The combination with track rails and supporting ties, of a series of spaced apart members having laterally flanged upper ends and carried by the ties parallel with the rails, plates supported upon the flanges of such members between and on the outside ot each track rail, and engaging means carried by the plates and adapted to be slid into and out of engagement with the flange edges of the aforesaid members.

4T. The combination with' traek rails and supportino' ties. ot1 a series of spaced apart inverted headed members carried by the ties parallel with the rails, plates supported upon such members between and on the outside of each track rail, having transverse slots located at each side of such members, and bolts extending through the slots of the plates to engage the aforesaid members for ad'instably securing` the plates in position.

5. The combination with track rails and supporting ties. of a series of supporting members extending' parallelly with the track rails Yand spaced apart, tread plates detachsecured thereto, an inclined plate secured to the outer end edges of the tread plates extending' at their ends adjacent to the track rail and extending at their lower edges into the track ballast.

6. The combination with track rails and supporting' ties and mud rails havingl their base flanges set vertically and carried by the ties at the inside of each track rail, of a series of tread plate supporting members carried by the ties parallel with the track rails and spaced apart. tread plates supported upon the supporting members. detachable connecting` means between the tread plates and supporting' members, and downturned flanges extending` from the lateral edges of the tread plates located between the track rails and over the upturned edge of the mud rail base flange.
